Insights

Repetitive behaviors and impulsivity are significant risk markers for self-injury, aggression, and destruction in children with severe intellectual disability. Early intervention strategies targeting these behaviors are crucial for this high-risk population.

Area of Science:

  • Child Psychology
  • Developmental Disabilities
  • Behavioral Science

Background:

  • Severe intellectual disability (ID) in children presents challenges, including self-injurious, aggressive, and destructive behaviors.
  • Early intervention strategies are increasingly supported for managing these behaviors in high-risk children.
  • Understanding predictive risk markers is crucial for effective intervention.

Purpose of the Study:

  • To determine the cumulative incidence and persistence of self-injury, aggression, and destruction in children with severe ID.
  • To investigate the relationship between these behaviors and risk markers: repetitive behaviors and interests (RRBI), and impulsivity/overactivity (O/I).

Main Methods:

  • A longitudinal study design was employed.
  • 417 children with severe ID were assessed by teachers.
  • Assessments were conducted twice, with a 15-18 month interval, measuring self-injury, aggression, and destruction.

Main Results:

  • Aggression, destruction, and self-injury showed high persistence rates (69%, 57%, 58% respectively).
  • Both RRBI and O/I were significantly associated with aggression, destruction, and/or self-injury.
  • RRBI and O/I significantly increased the relative risk for the cumulative incidence of these behaviors.

Conclusions:

  • Repetitive and restricted behaviors and interests (RRBI) and overactivity/impulsivity (O/I) are confirmed as risk markers.
  • These markers predict the onset of self-injury, aggression, and destruction in children with severe ID.
  • Findings support risk-informed early intervention for this vulnerable group.

Conduct Disorder01:28

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...

Aggression01:47

Aggression

Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...

Intellectual Disability01:29

Intellectual Disability

Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...

Bullying

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

Adler's Individual Psychology01:28

Adler's Individual Psychology

Alfred Adler, a prominent figure in psychology, founded the school of individual psychology. In contrast to Freud's emphasis on sexual or aggressive motives, Adler suggested that individuals are primarily motivated by their purposes and goals. He believed that people strive for perfection rather than pleasure. Adler argued that individuals could creatively act upon their genetic inheritance and environmental experiences to shape their own lives, emphasizing conscious motivation over...
